Abstract (en)
[origin: WO2020250206A1] A method of executing an instance (CI_1) of a smart contract (DP) through a blockchain shared among a plurality of nodes, the method including the following first step of serializing in the blockchain of the instance (CI_1) of that smart contract, and the following steps in cyclical succession: a second step of serializing a plurality of status files (CC_1, CC_2,... CC_i) each containing the state defined only by internal variables (f1, f2) of that instance at the end of a respective plurality of executions of the instance, said plurality of state files being temporally ordered according to the respective executions of the instance, a third step of deserializing in the RAM of a last state of the instance by deserializing at least one last state file (CC_i) from that blockchain, and a fourth step of deserializing the instance (CI_1) by valuing its second state as the last state, a fifth step including further execution of that instance (Cl_1).
